FOUNTAIN-PEN.

Specification of Letters Patent.

Patented Jan. 12, 1909.

Application filed April 2, 1908. Serial No. 424,716.

To all whom it may concern:

Be it known that I, FRANK E. WATERMAN, a citizen of the United States, residing at Parkersburg, in the county of Wood and State of West Virginia, have invented new and useful Im rovements in Fountain-Pens, of which the 'ollowing is a specification.

This invention relates to certain new and useful improvements in fountain pens and the object thereof is to provide a pen of such class in the manner as hereinafter set forth, whereby the fiow of ink to the pen point can be regulated as well as shut off entirely when occasion so requires and when shut off will prevent leakage of ink, whether the pen is carried on the person or laid upon a desk or other support.

A further object of the invention is to provide a fountain pen which shall be simple in its construction, strong, durable, efficient in its use, will provide a continuous and even flow of ink to the pen point when in use, inexpensive to manufacture, and having the parts so set up and arranged as to enable the ready cleaning thereof when occasion so requires.

With the foregoing and other objects in view, the invention consists in the novel construction, combination and arrangement of arts as hereinafter specifically described an illustrated inthe accompanying drawings, wherein is shown the preferred embodiment of a fountain pen in accordance with this invention, but it is understood that changes, variations and modifications can be resorted to which come within the scope of the claims hereunto a pended.

1:.- In the drawingsz-lhgure 1 is a vertical sectional view of a fountain pen in accordance with this invention when not in osition to be used. Fig. 2 is a sectional e evation of the fountain pen when in position to be used. Fig. 3 is a perspective view of the body portion of the en which constitutes the ink reservoir, and ig. 4 is a view looking towards one end of said body portion.

Referring to the drawings by reference characters, 5 denotes the body portion of the en which is cylindrical in contour and holowed out as at 6 to constitute a reservoir. The lower end of the body portion is closed as at 7 with the exception of a plurality of outlet channels 8 formed in the end 7. The upper end of the reservoir 6 is closed through the medium of a cap 9 provided with interior threads engaging with exterior threads formed on the body portion 5. The body portion 5 at its upper end is cut away to provide a shoulder 10 against which abuts the lower end of the cap 9. The diameter of the cap 9 with respect to the diameter of the body portion 5 is such that the cap 9 will form a continuation of the said body portion. The latter is further provided at its lower end with a depending annular extension 11 provided with exterior screw threads and said annular extension 11 is of less diameter than the diameter of the body portion 5 and is formed integral with the end 7 of the body portion at a point removed from the peripheral edge of said body portion 5. Formed integral with the end 7 of the body portion 5 and depending therefrom is a conical-shaped extension 12 formed with peripheral threads and said extension 12 is positioned approximately centrally of the outer face of the lower end 7 of the body portion 5. The diameter of the conical extension 12 at its upper end is such as to cause said end to terminate between the outlet channels 8. The conical extension 12 constitutes a valve for regulating the flow of ink to the pen point and for shutting off the flow of ink and in connection with the annular extension 11 constitutes means whereby leakage is prevented when the conical extension 12 is moved to a position to shut off the flow of ink in a manner as hereinafter set forth to the pen point. The conical extension 12 is further provided with one or more grooves 13 at its lower end to facilitate the supply of ink to the pen point.

The reference character 14 denotes a pen point coupling member and is provided at its upper end with an annular groove 15 with one wall thereof screw-threaded and the said annular groove 15 is adapted to receive the annular extension 11 whereby the coupling member 14 is connected with the body portion 5. The coupling member 14 at its upper end is furthermore provided with a conical-shaped opening 16 which has the wall thereof screw-threaded and is adapted to be engaged by the valve 12. The wall of the opening 16 forms a seat for the valve 12 when the latter is moved to closing position. The wall of the opening 16 is furthermore provided with a groove 17 to facilitate the flow of ink to the pen point. The lower portion of the coupling member 14 is formed with a socket 18 which is adapted to receive the pen point 19. Secured in the cou ling member 14 and projecting. under an upon the pen point 19 is a conducting tube 20 the upper end of which communicates with a passage 21 formed in the member 14 and opening into the lower end of the conical-shaped opening 16. The upper end of the member 14 is formed with an upwardly extending annular collar 22 adapted to receive the lower end of the body portion 5.

The pen further comprises a cap member 23 adapted to engage the coupling member 14 to inclose the pen point, as clearly shown in Fig. 1, when the pen is not in use, and adapted to embrace the body portion 5, as clearly shown in Fig. 2 when the pen is adapted for use.

The height of the conical-shaped opening 16 with respect to the length of the valve 12 is such that when the valve 12 is seated, as clearly shown in Fig. 1 whereby the supply of ink is shut off to the pen, an ink receiving chamber 24 will be provided, the walls of which are formed by the top edge of the member 14, the inner face of the flange 11, the lower face of the end 7 and the periphery of the valve 12. When the pen is to be used and the flow of ink is desired, the body portion is turned to shift the threads of the valve 12 out of en agement with the threads formed in the wall of the opening 16. This action elevates the body portion 5 and increases the area of the chamber 24, as clearly shown in Fig. 2. When the valve 12 is in the position shown in Fig. 2 a passage is formed therebetween and the wall of the opening 16 and owing to such arrangement the ink will then flow to the pen point as will be evident, the grooves 13 and 17 facilitating the flow of ink. By the construction set up the flow of ink can be regulated and in this connection it will be stated that the width of thepassage formed between the valve .12 and and provided- With-an outlet, said body pore the wall of the opening 16 can be increased or diminished as desired, depending on the extent the valve 12 is removed from the opening 16. When the valve is seated it prevents the flow of ink to the pen point and the flange 1 1 prevents leakage from the chamber 24.

Although the adaptation of the invention is shown in connection with a fountain pen, yet it is evident it can be utilized in connection with a stylographic or other form of pen embodying a reservoir. The coupling member 14 can have that extremity carrying the pen point so modified as to be readily adapted for a pen of the stylographic class, as it is egident that the invention does not reside in t e whic regulates the fiow ink from the reservoir to the writing point of the pen.

What I claim is 1. A fountain pen comprisin a hollow body portion constituting an in reservoir en point, but in that part of the pen I ition having extending from one end a conical screw-threaded valve and an annular screwthreaded extension, combined with a coupling member carrying a pen point and provided with an annular groove having the wall thereof screw-threaded adapted to receive said annular flange and further provided with a conical-shaped opening having the wall thereof screw-threaded and adapted to be engaged by the screw-threaded valve whereby the flow of ink to the pen point is shut off.
